STIRRU P.

SPECIFICATION forming part of Letters Patent No. 409,558, dated August 20, 1889.

Application filed May 8, 1889. Serial No. 309.978. (No model.)

To all whom it may concern.-

Be it known that 1, JOHN BULL, a citizen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Im provcinents in Stirrups; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to spring-stirrups; and it consists in certain improvements upon the stirrup, for which Letters Patent of the United States No. 367,696 were granted to me 011 the 2d day of August, 1887, which said improvements will be hereinafter more fully described, and particularly pointed out in the claims.

Reference being had to the accompanying drawings, Figure 1 is a side elevation of my improved stirrup. Fig. 2 is a similar View, but at right angles to the view shown in Fig. 1. Fig. 3 is a longitudinal sectional View on line 00 a: in Fig. 2. Fig. 4 is a similar view on line y y in Fig. 1, or a sectional view at right angles to the view shown in Fig. 3; and Fig. 5 is a perspective detail view of the metallic hood removed from the stirrup.

Like letters of reference denote corresponding parts in all the figures.

The letter A designates an ordinary stirrup, made of a single piece of wood bent into proper shape and having a metallic hood l5 fastened across its upper end, consisting of the side plates a a and the connecting crosspiece or top plate I). The side plates a a, as well as those portions of the wooden stirrupbody which face and are covered by the same, are slotted longitudinally, as shown at C, and the upper cross-piece or top plate I) has two longitudinal parallel slots D Done on each side of its re-en'forced middle part or bridge I).

Projecting downwardly from and secured in the under side of the bridge I) are three (or more or less) parallel rods E, encircled by coiled springs F, the lower ends of which project into and are retained within the sockets G in a movable block or bearing H, the ends of which are reduced to form guides I, which project into and through the side slots C--one on each side of the stirrup. The under side of the block H is rounded to form a convex bearing for the stirrup-strap J, and is provided with depending shoulders K K, which limit lateral motion of the doubled strap upon the bearing, and also prevent the sides of the strap from wear or chafing by contact with the sides of the stirrup. The two ends of the stirrup-strap are inserted through the parallel slots D D in the top of the hood B, after which they are brought together above the hood and connected by a fixed or sliding loop L.

From the foregoing description, taken in connection with the drawings, the advantages of my improved construction will readily be understood. It will be seen that the spiral springs are supported by the strap passing under the block or bearing, so that the strap takes up and sustains in a direct manner all the weight or pressure brought to bear upon the stirrup; also, that the doubled sides of the strap cover the springs on the sides in sueha manner as to protect them in a great measure from dirt, mud, and snow, so that they are not liable to become clogged up by mud or frozen snow, but will always work easily in all kinds of weather and on all kinds of roads. By the reduced ends of the hearing, which project through the slotted hood and sides, the block and springs are prevented from twisting, and the whole body of the stirrup will be sustained by the block whenever the springs shall become compressed sufficiently to depress the stirrup till the projecting ends of the block bear against the upper ends of the side slots C.

Having thus described my invention, I claim B, having" parallel top slots D D, and side Slots C O registering With slots in the stirrup, and provided With the depending rods E, coiled springs F, movable sooketed block or 5 bearing H, having reduced ends projecting through the slots in the sides of the stirrup and hood, and provided With downwardlyprojeeting shoulders K K, and stirrup-strap J, doubled around the movable block orbear- IO ing and having its ends inserted loosely through the parallel slots D D in the hood, substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing asmy own I have hereunto atfixed my signature I 5 in presence of two Witnesses.

JOHN BULL.
